iam going to be running 2 tanks one in the wheel well and one across the back seats.
iam woundering what size converter and gas carby ill need.
carby iam thinking impco 300A or 425.
but i have no idea on the converter whould it better to run a gra b2 or one impco recomends.
or are there beter brands then impco i dont really wanna run gra if i did id just put a delco com on it and run gas injection.
engine is worked over a bit and does around the 100rwkw mark on petrol

Grab a new gen Sprint Gas Mixer and matching converter.
Need to run a complex converter to control idle mixtures as well, as the mixer is a simple type with no idle mixture adjustment.
Mixer is said to be good for 380hp at the crank.
And it will bolt straight on to the top of any holley carb.
So you can fit a nice big 600DP, 600VS, or at least a 500 Holley.

What donut tank are you looking at fitting in the spare tire well?

i think its out of a commodore wagon its a little big but i have a big hammer lol
i may even plasma cut the well out and fit an ea falcon one in .
